What I'm looking for

I’m looking to join a growth-focused team where I can turn messy data into reliable dashboards, so we make faster, data-driven decisions across areas like sales, HR, and finance.

I build dashboards from data I can validate end to end—starting with SQL checks for daily transactions and moving into clear reporting in Excel and Power BI.

During my Data Analytics Internship at Timarcy Heritage, I automated weekly Excel reporting with Power Query, cutting manual work by 4 hours per week. I also helped track user signups, sales, and churn through dashboard work.

I’ve worked on projects across HR, sales, and finance—like an employee attrition dashboard using Power BI, Excel, and DAX, plus a sales performance dashboard in Power BI with dynamic filters and SQL/Python-backed analysis.
